In the first grid of the first row of the toolbox, there is still a card.

Li Yu glanced at 001, who was dedicated to studying, and asked the system to take out the cards.

On the card is a small glass bottle filled with blue liquid, with only one word written on it.

【Medicine】.

Li Yu, "What medicine? Poison or antidote?"

1551, "Unclear."

Li Yu stared at the card for a few seconds and couldn't think of a reason, so he asked the system to put the card back and click on another item.

This prop is very interesting, it is a backpack.

Li Yu scratched his face, suddenly thought of something, and jumped from the sofa to the ground.

001 has been working on two things. Hearing the voice of the young man running away, he followed up with the tablet, but was blocked by the bathroom door.

He stood outside the door for a while, opened his mouth to call someone, but found that he didn't know the young man's name.

He pursed his lips in annoyance, raised his hand and kept knocking on the door.

At this time, Li Yu just took out his backpack, turned his head and shouted outside, "I'm going to the toilet, wait a moment."

001 no longer knocks on the door, and keeps watching.

Li Yu was standing at the door, and threw all the things in the bathroom into his backpack by the shimmer of frosted glass.

Soap, shampoo, two towels, two large bath towels... The backpack with a small capacity should have been full long ago, but it was empty, with only the soap box that was thrown in at the end.

It was the first time that Li Yu got such a magical item, and excitedly threw an empty fist into the air, "Is this a bottomless pit of dissatisfaction?"

1551, "It seems that you try to take it out."

Things disappeared as soon as they went in, and Li Yu couldn't think of any other way except for the soap box, which was the bottom of the bag made of Oxford cloth.

With a thought, the towel fell to his feet with a pop.

He touched the backpack like a baby, and felt that it was not enough, and gave him a loving kiss.

This time the props are a treasure.

1551 was disgusted, "Tired."

Li Yu sneered, "You don't understand, with this thing, I can put the entire arsenal in it, and you will love it if you change it."

Suddenly thinking of something, he asked, "Why did you urge me to get the props before, you already knew that the backpack would fall?"

"I didn't know in advance, I just considered the prophecy of the prop." The system said, "This also depends on luck, in case a knife or a gun is sent down, it is also possible."

This is true.

When you leave the bunker, you will be surrounded by yellow sand, and with countless alien species, it is indeed very possible to put self-defense props on your hair.

Li Yu cherished the bag in his arms even more, "My luck in this world is much better than before."

1551, "Hopefully."

Li Yu, "..."

Outside the door, 001 waited and waited to see the young man come out, and began to feel uneasy.

When he hid in the warehouse alone before, day and night looking forward to the young man to see him, his heart was empty, and it could only be filled at night.

Now, the young man is separated from him, and his heart is still empty.

He thought that he had to watch people all the time, so that he would feel better.

001 thought for a while, raised his hand, and knocked on the door very lightly, as if he was looking for a sense of presence, and at the same time as if he was urging.

Li Yu, "Come on."

He took out all the things in the backpack, returned to the original position, stood there and calmed down his excitement for a few seconds before turning around.

On the frosted glass, 001 was lying on top of it, looking in with wide eyes.

Li Yu was also lying on the door, with his big eyes and small eyes, "001."

Finding that the strange figure on the door was a young man, 001 was startled and retreated with a guilty conscience.

Intuition tells him that peeking is bad.

Li Yu opened the door and came out, touched the little thing's head, and walked straight to the sofa.

He patted the vacant seat beside him, "Come here, sit down."

001 walked over with his small tablet, not forgetting to place his hands on his knees.

I don't know who learned this pose from. Li Yu hooked his lips and said mysteriously, "Do you have any precious things that you can put in my backpack temporarily."

He patted the empty backpack proudly, "It's very powerful, it can hold anything."

001 looked at the youth, then at the backpack, and asked earnestly, "What about me and you?"

Li Yu narrowed his eyes slightly, and it took a while to understand. He shook his head and said, "We are too big for anyone to fit in."

001 drooped his eyelashes in despair, and stroked his fingers on the sofa.

Li Yu didn't understand what was wrong with him, so he leaned over, pinched the man's earlobe and asked, "What's the matter with you?"

001 opened his mouth and said word by word, "I want to be put in."

Li Yu asked him why.

001 couldn't speak, turned his back, and poked the tablet with his fingers, eager to learn more.

Li Yu didn't bother him. He found a pen and paper by the bedside, listed the supplies he was looking for one by one, and marked the quantities at the back. He thought about taking some small things to rest tonight, and then starting tomorrow night.

The night was getting darker and sleepier.

Li Yu opened the food he bought before and put it in front of 001, "Eat if you're hungry, I'm going to sleep first."

001 still turned his back to the youth and said nothing, wondering if he was still angry.

Li Yu, "..."

Adolescence came early?

He helplessly rubbed the man's head, thought for a while, then bent down and kissed the tip of the man's ear, "Good night, baby."

001's ears moved, "Night, good night."

The hotel bed was big and soft, Li Yu hugged the pillow and rubbed his face, and quickly fell into a deep sleep.

001 learned that in the early morning, he was not sleepy at all, but his eyes were shining.

He walked gently to the edge of the bed, squatted at the head of the bed, grabbed the edge of the bed with both hands, moved his lips, and made a few breathy sounds.

Seemingly annoyed that his voice was too low, he pursed his lips, and this time his voice was a little louder, "In that case, in that case... Wherever you go, I can follow me."

After speaking a little shy, he buried his face in the quilt.

His hair was suddenly tossed, and he raised his head suddenly, his eyes widened in disbelief.

Li Yu was woken up by the system, and yawned sleepily.

Resisting the drowsiness, he leaned over and kissed the man's forehead, stretched out his hand and dragged him onto the bed, placing him in the vacant seat next to him.

Li Yu rubbed his eyes, his voice blurred, "If you can't get into the backpack, I won't leave you, I promise you..."

At the end, the voice was as small as a mosquito, 001 looked up and found that the young man was asleep.

He tentatively leaned over to the side, and seeing that no one was awake, he boldly leaned his head on the young man's shoulder, sniffed at the tip of his nose, and closed his eyes contentedly.

At half past three in the morning, 001 opened his eyes.

He lifted the quilt with his fingers, leaned in front of the young man's arm, stared at the already intact skin for a long time, rolled over and got out of bed, quietly turned out the window, and disappeared into the night.

Early the next morning, there was a knock on the hotel door.

The knocking on the door grew louder and faster.

Li Yu was forced to wake up, dizzy, and as soon as he lowered his head, he met 001's ignorant eyes.

In an instant, there was no sleep at all.

He hurriedly stuffed 001 into the quilt, feeling that it was inappropriate, and dug the person out of the bed and stuffed it into the closet.

"Shh, someone is coming, don't make a sound." Li Yu gave a serious warning and gently closed the cabinet door.

After tidying up his clothes at the entrance, he scratched his messy hair and opened the door.

"Brother Song?" Li Yu was surprised, "How did you know I was here?"

Qian Song, "I found it from the surveillance department."

Li Yu was shocked and asked the system, "Then I brought 001 back and was seen?"

1551, "No, I have dealt with the monitoring later."

The cold sweat that just broke out on Li Yu's back dissipated, and he turned to let Qian Song in, leaned against the wardrobe door and asked, "What happened?"

Qian Song, "Dead, the alien that attacked you and Kaelin is dead."

"Is it being dealt with by someone above?" After saying this, Li Yu felt that it was impossible.

Xenomorphs are not easy to catch, and every time you have to destroy a soldier to get a live one, it is impossible for someone who has died to come back to life, and it is impossible for the person above to kill a valuable experimental resource in order to pay Delson.

Qian Song, "I'm not sure, but the above told us to go back to the laboratory immediately."

Li Yu nodded and pushed the person parked at the door out, "Brother Song, wait outside, I changed the nightgown."

Before Qian Song could speak, the door slammed shut, almost hitting him on the nose.

Li Yu opened the cabinet door, covered 001's mouth, and pulled the person away from the door, "I want to go back to the laboratory, you stay here and study hard."

001 grabbed the youth's sleeve and didn't let it go, "No."

Li Yu tutted twice, took out the patriarch's stand, and his voice sank, "Obey."

001 let go of his hand reluctantly, and squatted on the sofa again, looking like he was being bullied.

Li Yu, "..."

After yesterday's turmoil, the atmosphere of the entire building of the research institute was a bit weird. When a few people passed by the door of 003, they would deliberately keep a long distance, for fear that something would pop out and tear people to pieces.

Li Yu frowned and asked Qian Song, "What's going on?"

Qian Song shook his head, "I don't know, I'll go to the lab and see."

Li Yu, "When they contacted you, they didn't say anything about the situation?"

"No, it's..." Qian Song recalled, feeling a little confused, "But the tone was very flustered and frightened. At first I thought it was a different species running out again."

While speaking, the two arrived outside the door of laboratory 003.

Qian Song swiped his card to enter the door and found a group of people surrounded the door of the isolation room, among which were several people from other departments wearing protective clothing.

Li Yu pushed aside the crowd and walked in, shocked by the situation in the isolation room.

Yesterday, the majestic and unblinking aliens who killed without blinking had their bodies and heads separated, blood all over the place, and they couldn't die any longer.

Li Yu asked, "Who discovered it first?"

"Zhang Zefeng." Someone replied.

"What about others?" After Li Yu finished speaking, he looked around again, and there was indeed no trace of Zhang Zefeng.

"I was called to assist in the investigation." The colleague in the laboratory pouted and sneered, "He was afraid that his status would not be guaranteed, so he came a long time ago and wanted to find Mr. Delson to save his senses. He heard that the professor was dead. Still not convinced, I went to the small laboratory in a rage, and the result..."

Zhang Zefeng's courage is indeed very small, and Li Yu asked, "Are you scared?"

"It's almost there, I fainted." The colleague said, "I only went in when I heard the movement outside, and was startled, and then notified the security department. Soon after, Zhang Zefeng was dragged out, even our The general manager of the institute is here.”

Li Yu once again turned his attention to the glass stained red with blood.

1551's voice trembled, "Do you want mosaic?"

Li Yu swallowed nervously and refused, "No need."

He got closer and found a small piece of relatively clean glass to look in.

The fracture on the xenogeneic neck is relatively flat, not like it was violently torn, nor like it was cut by a sharp tool.

On the ceiling, in addition to the small hole that was cut out by the alien nail yesterday, there is another hole, which is a vent.

It seems that someone sneaked in and killed the alien.

Xenomorphs have tighter muscle structures and heavier weights than humans, but according to the traces on the scene, the fight between the two sides is not too intense.

It can be seen that the people who sneak in are stronger than the dead aliens.

Li Yu thought of a person, but was not sure, "1551, I remember you can find out everything that happened in this world after we arrived in the mission world."

1551, "What do you want to check?"

Li Yu, "After I fell asleep last night, where did 001 go?"

The people who came to participate in the investigation were the same group of people who were in charge of investigating Delson's death.

Even if they knew that the air in the laboratory had been purified, they still refused to take off their thick isolation equipment, and they were humming questions through the gas masks that were in the way.

"After get off work last night, did anyone come back to the laboratory."

The person who asked the question should be the head of the investigation team, with a serious expression, but when his eyes fell on Li Yu and Qian Song, there was a little more fear.

"No one has come back." The researchers looked at each other, and finally sent one person to speak on their behalf.

The investigation team, "Apart from the xenogeneic species, is there any other experimental body in the laboratory?"

The spokesman said yes, and led the investigation team to each small laboratory to check it. When they came out, everyone in the investigation team had a dark face.

Li Yu picked his fingers and urged the system, "Do you have any eyebrows?"

The system voice hesitated, wanting to say something but not wanting to say it.

Li Yu, "Speak."

1551 muttered, "See for yourself."

Li Yu has an additional screen in front of his eyes, playing historical pictures.

001 After he fell asleep, he climbed downstairs along the window like a gecko with his hands and feet. The camera zoomed in and you could see that his fingernails were extended, and steel needles were generally inserted into the wall.

Li Yu was stunned for a while, suddenly remembering what he was when he asked the target last night.

At this moment, he still can't find the answer, but what can be confirmed is that 001 is not human, at least not completely.

Then why can he retain the shape of a human and live in a place without water?

Is it really as rumored that 001 is the descendant of humans and mermaids?

Li Yu put away his thoughts and continued to look back.

001 left the hotel, precisely avoided all surveillance, followed the darkest place, entered from the woods outside the institute, and then sneaked into the building.

After entering the building, he went to the bathroom on the first floor, skillfully dismantled the ventilation duct at the top, hooked the ceiling with both hands, and rolled his legs to get in.

Li Yu put his hands on both sides and gently tapped the side of his lower leg, "It seems that he drilled these places a lot when we didn't know it."

1551, "He wasn't a fool who didn't understand anything."

Li Yu said thoughtfully, "From the time I found out that he was picking up discarded chips in the garbage, I knew that he had a lot of things hidden in his heart."

1551 meant something, "Let's see, it's more exciting later."

In the light screen, the man crawled along the pipe until he reached the largest pipe running from the top floor to the bottom floor.

Li Yu also crawled through that pipe when he went to the Institute warehouse to steal something.

Because it was too difficult to get up, he still remembers it vividly.

But the same problem, when it fell to 001, became a breeze.

001's limbs are strong and strong. When he supported the pipes on both sides, Li Yu could clearly see that the lines on the arms had ups and downs, but they were not exaggerated, full of beauty of strength.

As for the legs, they were hidden in the trousers. was too embarrassed to look at them carefully last time, but now will make up for them in combination with a man's vigorous and agile posture. They should also have strong explosive power.

The long and narrow vertical pipe was quickly left behind by the man, and Li Yu was taken aback for a moment.

Immediately, something surprising happened to him.

After arriving at the floor where the laboratory was located, 001 did not act immediately, but crawled in the pipeline, closed his eyes, and mobilized his hearing and smell to capture some kind of information.

Li Yu, "What is he looking for?"

System, "You'll find out soon."

Li Yu scratched his head in his heart, as if he was watching an adventure movie, excited and nervous, eager to know the result.

After about a minute or so, 001 continued to crawl forward.

Li Yu frowned and asked the system to put a perspective view of the floor in the upper right corner of the light screen.

In contrast, it was found that 001 had reached the corridor outside the laboratory at this time.

He crawls fast, as if his hands, feet and knees had suction cups, and not a single slip.

When he was about to turn to enter the 003 laboratory, the man suddenly stopped without warning.

Li Yu frowned and was curious when he saw black bone spurs growing on the back of the other's hand.

The bone spur is not the same as the bone spur of the mermaid have seen before.

Although it is black, from other angles, it can be found that there is a little gold in it, with a metallic luster.

001 slashed the metal ventilation duct with a bone spur, and suddenly stretched his hand through the crack, grabbing the electrical conduit that was clinging to the duct.

The hard galvanized steel pipe was like a toy in his hand, and it shattered when squeezed.

Li Yu saw that he had pulled out the wire inside and cut it into two pieces with a bone spur.

At the same time, all the monitoring indicators in Laboratory 003 went out.

Li Yu's back was shivering, and the man had probably already understood the laboratory thoroughly in the few years he was left out by Dellson.

Perhaps without his help, 001 could rescue the three mermaids in his own way.

I don't know how long it took, the man in the pipeline was finally forced to stop.

In the unobstructed pipeline, there is an additional "wall".

That's the purification device set up to prevent the exhaled air from polluting the air in the bunker.

I saw his fingernails stretch out, easily piercing the pipe, hooking the blocked device casing, and pushing it up with brute force.

Seeing this, Li Yu already knew what he was looking for.

Li Yu, "He was looking for the alien that hurt me, so the alien was killed by 001?"

System, "Hmm."

It paused for a few seconds and asked carefully, "Do you now know why his danger level is two plus?"
